Malaysia is an important petrochemical base in ASEAN. The development of offshore oil fields, refining and processing, port oil tanker operations, and small-scale refining workshops generate approximately 62000 tons of oily sludge annually, with an oil content of 30% -62%, mixed with impurities such as crude oil residue, sand particles, and oil pollution. Among them, the large refinery in Kedah produces a large amount of oily sludge every year, which requires professional equipment for disposal. The surrounding waters of the country are vast, and the arbitrary discharge and simple disposal of oily sludge will seriously pollute the marine ecology and surrounding water systems, violating the Environmental Quality Act of 1974 and DOE regulatory requirements. According to relevant standards, the oil recovery rate of oily sludge must be ≥ 95%, and the treated wastewater must meet the discharge requirements of pH 5.5-9.0 and oil and grease ≤ 10mg/L. The residual oil content should be ≤ 0.3%, and it can be used for soil improvement or safe landfill. At present, the treatment process of oily sludge in Malaysia is relatively simple, mostly using natural sedimentation, simple incineration and other methods. There are problems such as low oil recovery rate, serious secondary pollution, and equipment adhesion. At the same time, mobile treatment equipment is needed in remote areas of the East Malaysia offshore oil fields to adapt to offshore operation scenarios, and there is an urgent need for treatment equipment that is suitable for local oil and gas industry needs, anti adhesion, low-cost, efficient and environmentally friendly.

China Yongle Environmental Protection Engineering has developed the "Ma Biao Efficient Anti stick Wall Pyrolysis" oily sludge treatment equipment: targeting the characteristics of oily sludge in Malaysia and the pain points of equipment wall sticking, it adopts a titanium alloy anti-corrosion and anti stick compartment+fully enclosed negative pressure pyrolysis structure, which can withstand high temperature, high humidity and saline alkali working conditions, effectively solve the problems of sludge wall sticking and equipment wear during the pyrolysis process, extend the service life of the equipment to 8 years, and adapt to microbial degradation assisted processes, which can further improve the efficiency of oil recovery and meet the research direction of local oily sludge treatment. The core is equipped with a triple process of "multi-stage screening+high-temperature anaerobic pyrolysis+oil-water separation". Firstly, 99.7% of sand particles and metal debris are removed through intelligent screening, reducing the difficulty of pyrolysis. Then, the oil is separated by high-temperature anaerobic pyrolysis at 860 ℃, with an oil recovery rate of 95.8%. The recovered oil can be directly sent back to refineries for refining or used as industrial fuel. The combustible gas produced by pyrolysis consumes 46% of the energy, achieving energy cycling; After deep purification treatment, the exhaust gas meets the discharge standards, and the treated wastewater meets the DOE emission standards. It can be recycled for cleaning or discharged into green belts, with a residual oil content of ≤ 0.27%. It can be used for soil improvement or safe landfill without secondary pollution, fully meeting local environmental protection requirements.

Adaptation to the entire industry chain scenario: In the large-scale refining plant in Kedah Prefecture, the daily processing capacity of large-scale centralized equipment is 100 tons, which has been installed and debugged and is about to enter the trial operation stage. It will be linked with the plant's oil supply system to form a "sludge oil energy" closed loop, improve resource utilization, and reduce production costs; In the offshore oil field operation area in western Malaysia, mobile equipment is deployed along with the drilling platform, with a daily processing capacity of 50 tons, specifically for the disposal of oil-based drilling mud and drilling cuttings, to avoid sludge transportation leakage and pollution of marine ecology, and to adapt to offshore operation scenarios; At the coastal ports of Kuala Lumpur and Penang, modular equipment with a daily processing capacity of 75 tons is used to handle oil tanker cleaning sludge on site. Efficient anti leakage design is adopted to prevent pollution of the marine environment and safeguard marine ecological security; In small oil refining workshops, mini equipment with a daily processing capacity of 9 tons is low-cost and easy to operate. The oil recovery income can quickly cover the investment and meet the operational needs of small workshops; Around the oil depot, small-scale equipment is used to complete sludge treatment on site, reducing storage and transportation costs and avoiding oil pollution of groundwater.

Exclusive service guarantee: The equipment has passed the DOE full compliance audit and the Malaysian petroleum industry environmental certification, adapted to local oily sludge treatment standards and emission requirements, assisted enterprises in completing compliance filing, and can cooperate with Malaysian oil and petrochemical companies to promote the reduction and resource utilization of hazardous waste. Establish service bases in Kuala Lumpur and Kedah, reserve oil resistant, corrosion-resistant, and anti sticking core spare parts, achieve 24-hour maintenance response in core areas, and provide on-site maintenance services for offshore oil fields; Provide bilingual operation training and process guidance in Malay and English, simplify maintenance processes, adapt to local operation and maintenance levels, and focus on training cleaning and maintenance skills for anti stick wall compartments; The equipment procurement cost is only 50% of similar products in Europe and America. The income from oil recovery and energy self-sufficiency can cover the investment within 8 months, helping the green development of Malaysia's oil and gas industry, safeguarding marine ecological security, and promoting the harmless and resourceful disposal of oily sludge.

Yongle Environmental Protection is mainly engaged in the research and development, production and sales of complete sets of technical equipment for organic solid waste disposal and comprehensive utilization. Production and manufacturing, domestic waste treatment equipment, tire pyrolysis equipment, medical waste disposal equipment, hazardous waste disposal equipment, and achieve efficient and comprehensive utilization of resources through independently developed low-temperature anaerobic pyrolysis equipment technology solutions.
